iPad silicone stand in Apple store

New prompt for an old question. Anyone know where I can buy something similar to the display they are currently using in apple stores (2013) for the iPads? They are some kind of silicone ring at an awesome angle for writing. Bonus points if you could charge an ipad through it (magsafe, why not?)

I asked the guy at the store and he said they were proprietary and would not be available for purchase... but I figured I'd ask. And apple, you should totally sell these...
